In a German-language press release, Starbreeze studios just announced that PAYDAY 2 sold 1.58 million copies worldwide in its first month. What's particularly interesting about this announcement is that 80% of those copies were sold digitally.
There are several factors that could be feeding into PAYDAY 2's digital popularity. The first PAYDAY game didn't have a boxed release, so existing fans were used to purchasing the series from a digital storefront. In addition, there were reported retail shortages of the game shortly after launch, as it proved more popular than its publisher expected. Still, the sales figures contribute to the growing evidence of digital gaming's popularity, not only on the PC, but also on home consoles.
